I'm “flow” the gripper sock. I’ll help your inner light shine through with my advanced features designed for performance and comfort. Here’s why you should take me home with you: My silicone sole and heel grippers will give you superior traction not only for pilates, barre and yoga but in sports like tennis or badminton where a firm grip is desirable, or even on slippery floors. My compression arch further enhances your support and fit. I’m made with luxurious organic combed cotton (GOTS certified) and stitched with a high-gauge 168N needle count, which makes me even softer and longer lasting. Regarding sizing, I come in 3 sizes suitable for either women or men. Please refer to the size chart image (attached) which shows the measurements (length) of each size in centimetres and the equivalent (approximate) shoe sizes in the UK, EU, and USA/Canada. hipSwan is based in Brighton, England and our distribution centre is in Northampton.
